B AS we convert mixed to improper fraction so 4 1/2 = 2 x 4 1 /2 = 9/2 2 1/8 = 8 x 2 1 / 8 = 17/8 Then we find equivalent fractions 9/2 = 9 x 4 / 2 x 4 = 36 / 8 and 17 / 8 will remain same as we know. Now we do subtraction. 36 / 8 - 17 / 8 = 36 - 17 / 8 = 19 / 8 = 19 divided by 8= Quotient=2, Remainder=3 so 2 3/8

Even there are no endpoints to two lines of symmetry in A option. And the figure in o has option C has a very large diameter and has only one line of symmetry

Actually the right Anwer is A but many children and admin are saying C so the thing is all about 1/5th money 💴 he spended and how much was left after 800 [the 1/5th of 4000] was subtracted from 4000

Ans 22:

Class : Class 4

Ans 23:

Class : Class 7
It is C because he spent one fifth of it so we have to add 800 because he earnt it.It is showing in the chart after he spent the money.

Ans 24:

Class : Class 5
The correct answer is 'A.3200' as he is spending one-fifth of the money in April then we have to subtract one-fifth of he amount(Rs.4000) he is having and when we subtract the amount Rs.4000 from Rs.800 the answer we will get is Rs.3200 which is in option 'A'

Ans 25:
